Originally, QueryList implemented Iterable and provided a Symbol.iterator on its prototype. This caused issues with tree-shaking, so QueryList was refactored and the Symbol.iterator added in its constructor instead. As part of this change, QueryList no longer implemented Iterable directly. Unfortunately, this meant that QueryList was no longer assignable to Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input, so this meant that QueryList was not usable (in a type sense) for NgFor iteration. View Engine's template type checking would not catch this, but Ivy's did. As a fix, this commit adds the declaration (but not the implementation) of the Symbol.iterator function back to QueryList. This has no runtime effect, so it doesn't affect tree-shaking of QueryList, but it ensures that QueryList is assignable to NgIterable and thus usable with NgFor. Fixes #29842 PR Close #33536 |
